示例1: BoldFormatStream
' This method accepts an input stream and a corresponding data format. The method
' will attempt to load the input stream into a TextRange selection, apply Bold formatting
' to the selection, save the reformatted selection to an alternat stream, and return
' the reformatted stream.
Private Function BoldFormatStream(ByVal inputStream As Stream, ByVal dataFormat As String) As Stream
' A text container to read the stream into.
Dim workDoc As New FlowDocument()
Dim selection As New TextRange(workDoc.ContentStart, workDoc.ContentEnd)
Dim outputStream As Stream = New MemoryStream()
Try
' Check for a valid data format, and then attempt to load the input stream
' into the current selection. Note that CanLoad ONLY checks whether dataFormat
' is a currently supported data format for loading a TextRange. It does not
' verify that the stream actually contains the specified format. An exception
' may be raised when there is a mismatch between the specified data format and
' the data in the stream.
If selection.CanLoad(dataFormat) Then
selection.Load(inputStream, dataFormat)
End If
Catch e As Exception ' Load failure return a null stream.
Return outputStream
End Try
' Apply Bold formatting to the selection, if it is not empty.
If Not selection.IsEmpty Then

End If
